Conducted by Nielsen and E-Poll Market Research, the rankings are determined by an ‘influential’ percentage, an “awareness” percentage, and an “N-Score,” Nielsen’s measurement for a player’s endorsement potential.

“For a backup quarterback to be talked about so much is incredible,” says Stephen Master, senior vice president of Sports for Nielsen, which conducted the surveys over the past several months in partnership with E-Poll, a market research firm in Encino, Calif. “But it is the biggest market.”

Olympic swimmer Michael Phelps finished second in the survey with 25% finding him influential; Jamaican sprinter Usain Bolt (23%) was third, while New York Yankees shortstop Derek Jeter (22%) was fourth.
